BEMOVABLE HORSESHOE-CALK.

Specification of Letters Patent.

Patented Apr. 4, 1911.

Application led March 18, 1910. Serial No. 550,150.

To all whom it may concern:

Be it known that I, W'ILLIAM H. KERN, a citizen of the United States, residing in Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Removable Calks for Horseshoes, of which the following is a specication, reference being had to the accompanying drawings.

This invention relates to improvements in removable calks for horseshoes, and the object of the invention, among other things, is to providemeans for detachably securing to the horseshoe proper in a simple yet e'flicient manner an adjustable frame carrying the calks, which device may be rigidly secured to the hoof and shoe of the animal, yet released again when required.

Figure 1 is a perspective view of my improved calk with the shoe; Fig. 2 is a top plan view of the calk and shoe combined and in locked position; Fig. 3 is a top plan view of the calk carrying frame in open position; Fig. 4 is a sectional view taken on the line mof Fig. 2, looking in the direction of the arrow.

Similar letters designate similar parts throughout the several figures.

Referring to the drawings, A represents the ordinary form of horseshoe.

B and C are two flat plates pivoted at O and rotating in the same plane and shaped to conform to the shape of the shoe when locked. They are adapted to have a scissorlike motion one upon the other so as to adjust B and C to the shoe. Secured to B and C, preferably integrally, are the clamps D, E, and F, Gr, respectively, slightly bent in- -wardly and corrugated, so as to engage firmly the shoe A as shown in Fig. 1.

H, H, H, etc., are the calks, inserted upon the under side of the plates B and C, as convenience requires and I have shown them secured to the plates B and C by the pins h, h, l1., clearly shown in Fig. 3.

Mounted upon the fore part of the plates B and C forming the calk carrying frame are the locking members K and L respectively, having the projections M and N meeting in substantial parallelism when the device is in locked position as shown in Fig. 2.

P is the locking bolt, threaded to receive the adjusting and locking thumb screw S as shown in Figs. 1 and 2. The bolt P passes through openings in the projections M and N and the bolt with the screw holds the parts together.

Other means may be used to lock and secure the plates B and C together.

The operation of my device is as follows: The plates B and C pivoted at O are expanded as shown in Fig. 3 and adjusted about the shoe and hoof of the horse. The locking members K and L are now drawn toward each other until the device has the position shown in Fig. 9. with the clamps D, E, F and G, all gripping the outer edge of the shoe as shown in Figs. l and 2. Then the bolt P is passed through the openings in the projections M and N, and the thumb screw is screwed down securely upon the bolt P in the well known manner, the whole operation having a powerful leverage grip through the clamps upon the shoe to rigidly attach the plates to the shoe.

This construction forms an exceedingly simple and efficient device and to detach the same the reverse of the operations hereinbefore described should be followed. The configuration of the plates B and C has the added feature of preventing the space inside the horseshoe proper from collecting material from the highway so that the shoe becomes balled, as for instance with snow, clay, etc.

What I claim as new and desire to secure by Letters Patent is the following, viz

1. In a removable calk for horseshoes, the combination with a horseshoe, of two horizontally reciprocating calli-supporting plates crossed and pivotally secured at the centers, the forward portion of each of said plates being oppositely disposed to the heel portion thereof, a plurality of vertically `disposed clamps attached to said plates to adjustably engage said horseshoe along its outer surface, projecting lugs at the toe end of said plates, and means to secure said lugs together when said clamps are fastened to said horseshoe, substantially as described.

2. In a removable calk for horseshoes, the combination with the horseshoe A, of the plates B and C, crossed and pivotally secured at O, the forward portion of each of said plates B and C being oppositely disposed to D, E, F, and G, to said horseshoe A, subthe heel poition thelieo, eacbdplate liagirllg stantially as described.
